Model and memory

How a long-lived system can keep its history: a model at work, a memory that outlives the conversation, and checked rules between them. Scroll through the chapters.

Chapter 01

A single conversation

Within one interaction, a model can use its context well. When the interaction ends, the context is gone — and with it what was learned, decided and promised.

Chapter 02

A memory that persists

Events are written to a memory that outlives the conversation. Each record keeps where it came from and when it was known, so the history can be read back later, in order.

Chapter 03

The model proposes, the memory verifies

What a model writes is a proposal. Checked rules decide what becomes a record. Everything else is kept, but marked as the model’s own words — never as a fact or a decision.

Chapter 04

What was known, and when

Every record keeps when it became known. So the memory can answer two different questions — what is true now, and what was known at a given moment — without guessing.

Chapter 05

Revision without rewriting

When a conclusion changes, the correction is added as a new record that points back to the earlier one. The earlier view stays in the history, so the path between them is never rewritten.

Chapter 06

Memory that outlives the model

Models can be replaced. The history and the checked rules belong to the system, so a new model starts from the same memory — nothing lost, nothing rewritten.

Continuity Over Time

Intelligence is not only a sequence of answers. Some problems require coherence across time.

Adaptive Depth

Different problems may require different levels of reasoning effort.

Uncertainty and Revision

An LLM should be able to revise conclusions when stronger evidence appears.

Reasoning and Resources

More computation is not always more intelligence. The value of additional reasoning matters.
